| 摘 要： | 首先分析波浪腹板阶形柱计算长度系数计算的相关问题,理论推导过程中考虑剪切变形对其稳定性的影响,得到考虑剪切变形时计算长度系数计算的精确公式,并与不考虑剪切变形的计算公式(GB50017—2003《钢结构设计规范》)以及有限元计算结果进行对比,从而得出了CECS 290∶2011《波浪腹板钢结构技术规程》中对于波浪腹板阶形柱计算长度系数计算的取值原则。其次,对波浪腹板阶形柱在侧向荷载作用下的变形进行分析,得到计算波浪腹板阶形柱侧向变形的计算公式。另外,根据波浪腹板阶形柱的特殊性,对波浪腹板阶形柱连接处的肩梁构造与计算方法进行阐述。

| Abstract: | The effect of shear deformation in singly-stepped sinusoidal corrugated web columns on the effective length factors is analyzed,and theoretically derived formulation was presented firstly.Compared with approximately "The Code for Design of Steel Structures"(GB 50017—2003) and the FEA results,it was concluded that the verification of global stability in the singly-stepped sinusoidal corrugated web columns is proposed by combing the effective length factors given by GB 50017—2003 with the design formula from Technical Specification for Sinusoidal Web Steel Structures(CECS 290∶2011) which reflects the effect of shear deformation of corrugated web.And the formula for calculating the lateral deformation of singly-stepped sinusoidal corrugated web columns was given.Finally,the structural construction details and design of shoulder-beam of singly-stepped column were introduced. |
